hUBRiCATOR'.

SPECIFICATION forming part of Letters Patent No. 279,120, dated June 12,1883.

Application filed September 30, 1882. (No modelii To to whom, it mayconcern I Be it known that I, J OSEPH M. BATTIN, Jr, a citizen of theUnited States, residing in the city of Newark, Essex county, New Jersey,

have invented certain new and useful Ini-' provements in Lubricators,fully described and represented in'the' following specification and theaccompanying drawings, forming a part of the same. I

This invention consists in an improved construction, herein shown anddescribed, for that class of lubricators adapted to operate under'apressure of steam and to feed a regulated amount of oil into anysteam-receptacle.

The construction will be understood from the annexed drawings, in whichFigure 1 is a central vertical section of a lubricatorprovided with myimprovements. Fig. 2 is a detached view of themai'n stem or conductingtube. Fig. 3 is a'section of the same j List above the oil-outlet (1.Fig. 4 is a section of the same at the center of the transverse oil.passage or u sists in a screw-rod arranged to stand across .thetransverse opening 0 when turned around outlet (1; Fig. 5, an end view,and Fig. 6 an edge view, of the guide-plug; and Fig. 7 a detached viewof the glass tube. The section shown in Fig. 1 is taken in aplane withthe oil-outlet shown at (Z in Fig.2, and the stem in the latter figureis viewed ninety degrees 1:107110116 position shown in Fig. 1.

The construction is intended' to obviate th use of crooked connectionsfor the oil and steam passages, which are very liable to become fouledwith the hot oil, and to secure a form for every part, so that it couldbefini shed in the turning-lathe and the cost thereby reduced. Theseobjects are secured by mounting the receptacle A upon a central stem, BC, the part B extending below the part A, and

' the part 0 entering the receptacle or oil-cup A and reaching nearly tothe top. The parts B and C will be termed stems B and (I when referredto separately herein, while the whole stem will be called stem B O. Thestem B is made a little larger than the stem 6 to secure a shoulder, s,and atight joint at the" bottom of the cup A, into which it is screwed,and is provided with a threaded bore, D, at the point where it entersthe cup, into which bore is fitted, a screw-p1ug, E, constructed tointroduce the steam into the cup and to 0011- duet the oil therefrom bypassages readily aced ,with holes I for viewing the interior of the *aninternal valve.

cessible from the top of the cup when the covusual manner, and with awoodenknob, a, at

the top, as in many similar cups.

The stem B is provided with a removable screw-coupling, G, at thebottom, and is made hollow for the introduction of a glass tube, H,which is fitted to compressible packings b at each end to be clampedsteam-tight when the coupling upon the lower end of the stem is screwedup close. The stem B is also providglass tube. The construction'of theplug E is shown in Figs. 5 and 6, and consists in a threaded cyl inderflattened upon two sides, and having a transverse ope11ing,,c, arrangedto intersect a central bore, 6, extending through the whole plug andprovided with a screw-thread to fit The valve a. is shown in Fig. 1,andcon-.

by a head projecting above the upper end of the stenrC. The upperend ofthe screw-rod a is shown provided with a hollow metallic cap, J, adaptedto cover or shield the vertical passage in the top of the stem 0, andthus pre vent the introduction of' oil orforeign substances into thepassages f, formed by the flat places on the plug E, between the latterand the threaded bore of the stems B and C.

' The cap may beu-oughened on the outside, it needed, as it serves forthe turning-head of the valve (1.

The passages fare shown in Fig. 4, which shows the coincidence of thetransverse opening in the plug at o with two holes, (I 11, formed in thesides of the stem 0 at a level with the bottom of the oil-cup A. Thetransverse opening 0 is made parallel with the flat sides of the plug,and thus secures a connection between the interior of the plug at e andthe oil in the cup A, which is thus able to flow out of the cup at c, asindicated by the arrow 0'. The flat sides being formed on the outside ofthe plug at ninety degrees from the openings 0, the

passages f have no connection with the latter,

but connect the bore of the glass tube H with the bore of the stem 0 bystraight vertical apertures, easily cleaned if obstructed by dirt. Bythe removal of the valve-stem a when the cover F is removed, the centralbore, (2, may be similarly cleaned.

The operation of my device is as follows: The cap F being removed, thecup A is filled with the luln'ieatingfluid, the valve (1 being screweddown to close the transverse opening 0, and the cap J preventing thefalling of oil into the inside of the stem 0. The valve a is thenadjusted to permit a regulated escape of oil to flow out ofthe bore 0 byits gravity when hot, and its head J'may be marked in agree ment withsome mark upon the mouth of the cup A, to indicate the best position ofthe valve when adjusted by experiment. The whole lubricator is of coursecut off from the steam pipe or chest which it is intended to lubricate,while being filled, by a suitable cock or stop below the coupling G, andas soon as the stop is opened the steam is admitted to the bore of theglass tube, whence it passes above the oil through the passages f andthe interior of the stem (2 and the aperture between the top of the sameand the cap J, as at arrowsJ. The pressure thus produced upon the top ofthe oil, which is of course equal to the pressure in the steam-vessel towhich the lubricator is attached, is balanced by the entrance of steaminto the bore of the plug at whence it presses upon the oil through theopenings 0. These openings being reduced to narrow slits by the valve awhen the appa 'atus is in practical use, the steam has no tendency toenter therein, because opposed by a precisely equal pressure operatingupon the top of the oil, and the latter is therefore at liberty todescend through the bore 0 at the natural rate induced by its weight.The passage of. the oil is easily perceived as it drops from the lowerend of the plug E,whiclr is extended into the glass tube opposite theopenings I for that purpose, and the flow reg ulated by turning the headJ when the cock in the connecting-pipe is closed and the cover Fremoved. p

I am aware that ,lubricators' have been devised in which theregulating-valve could be operatedwithout removing the cover of theapparatus, and in which the flow of the oil could be distinctlyobservedby its passage upward through a column of water; but the ob jectof my invention has been to combine the greatest simplicity ofconstruction with facility for cleaning and freedom from derangement. Bymy construction no water is used to observe the flow of the oil, and allwater condensed in the receptacle A would immediately sink. to thebottom of the same and work out through the apertures c and e. Theconstruction is therefore perfectly drained, and not liable to freeze upwhen left at night, and is adapted to work in situations where the steamdoes not operate under the pressure referred to above. The plug E isreferred to herein as made apart from the stem B O, and suchconstruction is the most convenient in practice; but it is obvious thatif the same were cast in one piece with the stem, holes could be coredor drilled in place of the passages ff, and that-the holes or transverseopenings (1 (I could both be produced atthe same time by drilling acrossthe stem at the proper point.

Having thus described my invention, I claim the same in the followingmanner:

1. The combination of the cup A with the central stein, B 0, having asingle opening at the bottom and provided with the holes (I (I,

and with the plug E, constructed with holes (1 c and c, and arranged toform passages ff inside the stem (1, the whole substantiall; as shown,and for the purpose set forth.

2. The combination, with the plug E, having holes 0 e and e andflattened sides, of the stem B 0, cup A, and screw-rod and valve (I,provided with turning-head, substantially as shown and described.

3. The combination, with the stem B G and the vplug E, construct-ed andoperating with the cup A, as described, of the screw-rod a and turninghead or cap J, arranged to cover the mouth of stem 0, as and for thepurpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
